Question
Refrigerant vapor rejects 70 kW of
heat as it passes through an air-
cooled condenser. The condenser has
an air-side area of 210 m2 and based
on this area, has an overall heat
transfer coefficient of 0.037
kW/m2.°C. Cooling air flows at a rate
of 7.59 kg/s. If condensation of the
refrigerant occurs at 55°C, what is the
outlet temperature (in °C) of the air?
Take the specific heat of air to be 1.02
kJ/kg.°C.
